1. Field of the Invention
The invention relates to an electronic device and, more particularly, to components of a user input.
2. Brief Description of Prior Developments
Future product concepts for hand-held portable electronic devices are expected to have multiple modes and orientations of use; creating additional user interface complexity. Conventional keymats in hand-held portable electronic devices, such as mobile telephones for example, are typically designed for use in portrait mode only or landscape mode only. This is a problem when the product is also intended for use in the other mode because the keymat is no longer familiar and intuitive to use. For example, some conventional mobile telephones are able to change from a telephone mode having a portrait orientation of the device in the hand(s) of a user to a camera or movie mode having a landscape orientation of the device in the hand(s) of the user. Current keymats do not change to reflect this change in orientation and change in use modality.
Previous solutions include phone soft keys where the key relates to an on-screen menu choice. A touch screen can be used to provide the user with a changing user interface (UI). Other options have included printing all the alternative graphics onto the keys, but this increases visual complexity and confusion. U.K. Patent Application No. GB 2,396,845A discloses ideas for putting tiny displays into keys. However, this has not become a reality due to technology cost limitations.
There is a desire for a new type of user input section for an electronic device which can display indicia in different orientations, be intuitive for users to use, but also to be cost efficient to manufacture.
In accordance with one aspect of the invention, a user input section for an electronic device is provided including a keypad display, a key, and a sheet member. The keypad display is adapted to change display of indicia on the keypad display between at least two different display modes. The key has a user depressible top section located above the display and a bottom section extending below the display. The sheet member includes a main section and a key support section connected to the main section by a living hinge. The main section is substantially stationarily connected to the keypad display. The key is connected to the key support section such that the key is adapted to move relative to the keypad display and the main section with rotation of the living hinge of the sheet member.
In accordance with another aspect of the invention, a user input section for an electronic device is provided comprising a keypad display, a keypad board, and a plurality of keys. The keypad display is adapted to change display of indicia on the keypad display between at least two different display modes. The keypad display has a plurality of spaced display areas. The keypad board has resiliently depressible key domes. The key domes are located beneath the keypad display and are at least partially offset from respective ones of the display areas. The plurality of keys extends above the keypad display and adapted to actuate the key domes when the keys are depressed by a user.

The key support sections are adapted to have the user input keys connected thereto to provide pivotable movement of the keys relative to the main section with rotation of the living hinges.
In accordance with another aspect of the invention, a user input keypad display is provided comprising a plurality of spaced discrete display areas having respective selectively illuminated indicia; and slots in the keypad display forming a plurality of cantilevered fingers. Each of the cantilevered fingers comprises at least a portion of a respective one of the display areas.
The foregoing aspects and other features of the invention are explained in the following description, taken in connection with the accompanying drawings, wherein:
Referring to
The device 10 generally comprises a housing 12, a front side with a display 14 and a user input section 16, electronic circuitry 18 inside the housing and operably coupled to the display 14 and the user input (UI) section 16, and a camera 20 on a rear side. In this embodiment the electronic circuitry includes, for example, a transceiver, an antenna, a microprocessor, a memory and other components convention to a mobile telephone having a camera.
The UI section 16 generally comprises a keypad section 22 and a control section 24. The keypad section 22 comprises a keypad having conventional keys with alphanumeric indicia for telephone use, such as an ITU-T (International Telecommunication Union-Telecommunication Standardization Sector) keypad for phone dialing. An ITU-T keypad has a keypad layout utilizing twelve keys 12. The ITU-T keypad associates letters of the alphabet with the numbers on the keys 12 of the keypad. By example, the number “2” key carries the letters ABC, the number “3” key carries the letters DEF, etc., as is well known. Other types of letter to number arrangements used in key layouts include those disclosed in U.S. Patent Application Publication No. 2006/0103623 which is hereby incorporated by reference in its entirety. The control section 24 can include, for example, a joystick, soft keys, and/or dedicated operation keys.
As noted above,
Referring now also to
The keypad section 22′ of the user input section of the device 10′ generally comprises a keypad display 26, keys or key caps 28, and a sheet member 30. The display preferably comprises a flexible electronic display. ‘Flexible’ display technologies are relatively young. One of the features of the invention is the proposed use of this young ‘flexible’ display technology to provide a new and improved user interface. However, in an alternate embodiment any suitable type of display could be used.
One type of flexible display can comprise using a reflective PN LCD or TN LCD display on a plastic substrate. The LCDs can be supplied by Citizen Display Co. LTD. This technology is applicable to all the solutions described herein. In one embodiment, a TN LCD is combined with either a flexible EL lamp or thin silicon lightguide and LEDs to provide illumination. In another embodiment, for the PN LCD, front lighting can be provided in which light from LEDs is carried through a mobile telephone cover and clear keycaps to illuminate the display.
The invention provides a mechanical solution to the problem of achieving changing graphics on a keymat of a portable electronic device. The invention can consist of a keymat with changing graphics to simplify complex functionality and problems caused by switching product orientation. The invention is unique as it can combine a single changing graphics display with a conventional keymat that can use offset key domes to achieve button tactility.
As seen in
In this embodiment the top section 40 of each key 28 has a general L shape. The general L shape is formed by a first leg 46 and a second leg 48. When the device 10′ is in its portrait orientation, as seen in
When the device 10′ is in its landscape orientation, as seen in
As seen in
The sheet member 30 is located above the keypad display 26. The sheet member 30 comprises apertures 52 which form windows to allow a user to see the display areas 50 of the keypad display 26. The sheet member 30 also comprises apertures 54 for each one of the keys 28. Portions of the keys 28 are able to extend through the apertures 54 between the top section 40 and the bottom section 42 of the keys. As seen best in the partial, enlarged view of
The top sections 40 of the keys 28 are located on top of the sheet member 30 on the arms 62. The arms 62 are able to resiliently deflect inward, in a general cantilever fashion, when a user depresses the keys 28 inward. The sheet member 30 forms a user input structural support sheet for the user input keys 28. The main section 30 is adapted to be assembled into a user input of an electronic device in an assembly with the keypad display 26. The arms 62 form a plurality of key support sections. The arms 62 also form respective living hinges with the main section 64. This provides pivotable movement of the keys relative to the main section with rotation of the living hinges (deflection of the arms 62).
In this embodiment the key domes 38 are located under the second legs 48 of the keys 28. This is offset from beneath the display areas 50. When the user presses against one of the second legs 48 to actuate a key, its respective key dome 38 is actuated. Because of the attachment of the keys 28 to the main portion 64 of the sheet member 30 by the living hinges, when the user presses against one of the first legs 46 to actuate a key, its respective key dome 38 is also actuated; even though it is at least partially offset from beneath the first leg 46.
The sheet member 30 is connected to the keypad display; at least indirectly if not directly. The keypad display 26 is preferably at least partially a reflective display. As noted above, the sheet member 30 is located above the keypad display 26. The sheet member comprises a bottom surface forming a light reflection surface for reflecting light onto the keypad display. Thus, in addition to forming a support for the keys 28, the sheet member also forms a light reflector for the reflective keypad display. However, in an alternate embodiment, the sheet member might not form a keypad display reflector.
Referring also to
The slots in the keypad display 78 allow the keys 74 to be mounted on the fingers 84 of the keypad display 78. More specifically, the fingers 84 are received in the center apertures 86 of the general ring shaped keys 74. When a user depresses one of the keys 74, the bottom sections 82 depresses its respective the key dome 38, and the finger 84 can move freely relative with the key 74 in the center aperture 86.

In the embodiment shown in
In the embodiment shown in
The examples described above illustrate three ways of implementing the concept of a changing graphical keymat. The first embodiment described above includes the structural use of a thin flexible metal sheet member as a living key hinge and light reflector. This embodiment also provides a method for front lighting the reflective display and illustrated the concept of offsetting key domes with a hinged key cap design. In the first embodiment, the invention can use a thin film (electrophoretic) flexible display sandwiched between the keymat and the printed circuit board (PCB). The display is visible through or around the keys and provides all the graphical information. The key caps or keys actuate the key domes by bridging the display and connecting to offset domes. The concept of using offset key domes within the context of a changing graphical keymat allows a much larger display area and a greater amount of information to be visible to the user. The use of offset domes also isolates any forces, generated by pressing the keys, away from the display helping reliability and display life.
As shown in the second embodiment (
Future hand-held portable electronic devices are expected to have multiple modes and orientations of use; creating additional user interface complexity. Conventional keymats are typically designed for use in portrait mode only. This is a problem when the product is also intended for use in landscape as the keymat is no longer familiar and intuitive to use. Products change to camera or movie modes, current keymats do not change to reflect this.
The invention can consist of a keymat with changing graphics to simplify complex functionality and problems caused by switching product orientation. The invention can combine a single changing graphics display with a conventional keymat that can use offset key domes to achieve button tactility. The first two embodiments solve issues with current thin displays, including designs to prevent damage to the displays from pressing through them. The first embodiment shows a solution using a novel hinge mechanism which allows a key cap to straddle the U shaped display. The second embodiment shows a solution to isolate all the pressing forces away from the finger display. The invention also covers the display of icons in both landscape and portrait orientation, and the display of hidden keymat functions (camera, music, movies etc). The different sets of indicia could be shown based merely upon the mode of the device. The different sets of indicia do not need to have different orientations. They could have the same orientation. For example, showing a first set of telephone key indicia when the device is in a telephone mode, showing a second set of digital camera key indicia when the device is in a digital camera mode, and showing gaming key indicia when the device is in a gaming mode. The first and second sets could be in a first orientation while the third set is in a second orientation; or all three could be in the same orientation. This are merely examples and should not be considered as limiting.
The solution in the second embodiment differs because there is only one display which is split into fingers that pass through hollow key caps.
U.K. Patent Application No. GB 2,396,845A have individual displays inside each key. It has been demonstrated that the solution in
It should be understood that the foregoing description is only illustrative of the invention. Various alternatives and modifications can be devised by those skilled in the art without departing from the invention. Accordingly, the invention is intended to embrace all such alternatives, modifications and variances which fall within the scope of the appended claims.
